CONDENSING MECHANISM FOR CARDlN G-ENGINES.

SPECIFICATION forming part of Letters Patent No. 409,211, dated August20, 1889.

Application filed June 15, 1886. Serial No. 205,286. (No model.)

To (tZZ whom it may concern.-

Be it known that I, GEORGE LAYNG, a citizen of the United States,residing at \Vorcester, in the county of IVorcester and State ofMassachusetts, have invented a new and useful Improvement in CondensingMechanism for Carding-Engines, of which the following is aspecification, reference being had to the accompanying drawings, inwhich Figure 1 is a front elevation of a cardingcngine, showing suchparts as embody my present invention. Fig. 2 is a side elevation of aportion of a finisher-card, the gearwheels by which the upper pair ofdrawingrolls are connected having been omitted. Fig. 3 is a top view ofthe condenser, shown in elevation in Figs. 1 and 2 and with the upperwinding mechanism omitted. Fig. 4 is a detached view of one of thetransverse plates supporting the twisting mechanism. Fig. 5 is asectional view, on a larger, scale of the operating parts employed indrawing and twisting the sliver 01' roping,with the supportingframe-work omitted. Figs. 6 and 7 are Views of the roll-carrying leverby which I adjust the pressure upon the sliver during the operation oftwisting, and Fig. 8 represents the stand supporting the intermediategear connecting the drawing-rolls.

Similar letters refer to similar parts in the several views. f

My inventionrelates to that part of a carding engine known as thecondenser, in which the sliver or roping which has passed the successivecarding operations is slightly drawn and twisted preparatory tospinning; and my invention consists in providing a series of beltsplaced between the slivers or ropings and at an angle thereto with theopposing surfaces of each pair of belts acting upon the slivers to twistthe same; in the combination, with twisting mechanism, as described, ofapair of drawing-rolls by which the slivers are drawn and also held fromrotation; in providing means for adjusting the pressure of thetwisting-belts upon each individual sliver, and in certain details ofconstruction and arrangement of the operating parts, as hereinafterdescribed, and set forth in the claims.

In the accompanying drawings, A denotes the frame, B the main shaft, 0the main cylinder, and D D the upper and lower doffers, from which theslivers or ropings are taken by reciprocating combs D (Shown in sectionin Fig. 5, but omitted from the other views to avoid confusion.

Instead of a reciprocating comb other known devicessuch as a wipe-rollor a rotating comb1nay be employed The operation of carding and offorming a continuous roping or sliver upon what is known as afinisher-card is well known and requires no extended description.

The mechanism forming the condenser, and which embodies my presentinvention, is supported in the rectangular frame E, attached to the mainframe-work A. In front of each of the doffers I place the rolls F F,journaled in suitable bearings in the framework and in proper positionto receive the sliver from the rings of the doffers. The rolls F F maybe plain, or fluted, or covered, as the character of the work mayrequire. Above the roll F, I place the weighted roll G, held in openbearings a a, Figs. 2 and 3, and above the roll F, I place a series ofshort weighted rolls II, similarly held in the open or hooked bearings19, each sliver having a separate roll. The rolls F are rotated by thedoffers D D through gears D and F Fig. 3, and the roll F is rotated bythe roll F through the gears F and. F and the intermediate gear F whichis supported upon a stand F, Fig. 8, attached to the crossbar E, therolls F and F being of different circumferential speed. The intermediategear F is held upon a stud f, which is held in a slot f in the stand Fallowing the stud f to be adjusted in the slot, and the stand F islikewise held on the cross-bar E by a bolt f, which passes through aslot f in the stand, allowing the stand to be adjusted on the crossbar,and thereby allowing the size of the gears F and F to be changed and therelative speed of the drawing-rolls varied.

Connected to the frame E and extending transversely across the machineand between the rolls F F are plates I, one of which is shown in Fig. 4.Slits c are formed in the upper edges of the plates I to allow theslivers to pass from the roll F to the roll F, and studs held in platesI at d d carry small flange-pulleys J J, upon which the belts K areplaced in proper position to bring each sliver between the outer andopposing surfaces of each adjacent pair of belts. To the lowerflange-pulleys J, I attach the bevel-gears L, each engaged by abevel-gear L on the shafts L driven from the pulley L on the main shaftthrough the flanged pulleys L on the shafts L The shafts L areconveniently supported by arms L, Fig. 2, attached to the transverseplates I. A rapid motion is thus imparted to the belts K in thedirection of the arrows in Fig. 1, where a portion of the machine isomitted in order to disclose the construction of the twisting device.Upon the slack side of each belt, in contact with a sliver, I place aroll N, held on the free arm of a lever N, pivoted to the plate I by abolt and nut or a screw by which it may be adjusted and tightened,thereby regulating the pressure of the roll N against the belt andconsequently the pressure of the belt upon the sliver. The opposingsurfaces of the belts in contact with the sliver move in oppositedirections, as shown by the arrows in Fig. 1, thereby providing arolling motion upon the sliver, which, being held by the roll F and itsweighted roll G, becomes twisted, the amount of twist being determinedby the relative speed of the belts and that of the sliver between them.The upper holes d in the plates I, Fig. 4, are. elongated vertically toallow the belts to be tightened.

From the front drawing-roll F the slivers pass over the bar 9 to thewinding mechanism placed upon the top of the rectangular frame E, andconsisting of the rotating drum M, upon which the section-spool M rests,and the guide-bar M having a traversing motion to lay the slivers evenlyupon the sectionspool. The lower slivers pass over the bar g to asimilar winding mechanism placed beneath the drawing and twistingmechanism just described, and which in the present instance is attachedto the floor. The windingdrums are each rotated by a belt M from thepulley P on the shaft of the front drawingroll F, the relative size ofthe pulley P and of the pulleyP on the drum M corresponding with therelative diameters of the drum M and roll F.

The winding mechanism is substantially like that in ordinary use; but itis customary to place the winding mechanism directly in front of thecondenser to which the slivers are led in a straight line.

In my improved machine the winding mechanism is placed above and belowthe condenser and the direction of the slivers is changed by means ofthe bars g and g, thus rendering the machine more compact and occupyingless fioor space and permitting free access to the condenser in order topiece broken ends or adjust the operating parts.

Heretofore the operation of condensing the sliver or roping as it istaken from the rings of the doffer has usually been performed by passingthe sliver between a series of leathercovered rotating rolls, to which alongitudinal reciprocating motion is given; or the sliver has beenpassed through a rotating tube between drawing-rolls or between beltsrunning in the same direction as the sliver and having a lateralreciprocating motion.

In my improved machine I employ a pair of belts for each sliver, therebysecuring an independent action of the belts upon each strand andenabling the pressure exerted upon each strand to be adjusted, asdesired, and I also move the surfaces of the twistingbelts at rightangles to the axes of the drawing-rolls by which the strands of ropingare held from rotation.

The mechanism for drawing and twisting the slivers from the upper andlower doffers D and D is substantially the same, and therefore anydescription of one will apply to the other. I have shown and describedbut one series of twisting-belts K and two pairs of drawing-rolls F andF; but I do not confine myself to the use of but a single series ofbelts, for additional pairs of rolls may be employed and the slivers maybe subjected to successive operations of twisting bet-ween each pair ofrolls in case the character of the work re quires. Such use ofadditional rolls and belts would obviously come within the scope of mypresent invention. Neither doI confine myself to the specific method, asshown, of actuating the belts, as other well-known methods v willreadily be suggested, to those familiar with this class of machinery.
